l In Sweden June 3, 1932 Y 15 Claims. (Cl. 131-45) This invention relates to improvements in cigar-'wrapping mechanisms. y

A In cigar wrapping Amechanisms considerable dfliculty has been experienced in controlling the flag of theV wrapper after it' has been released from the wrapper support and before it is completely wound about a cigar Vbunch and on providing guides such asextensions of the tension platefor such purpose the wrapper nag will be subjectedV to an injurious dragging action by engagement with underlying surfaces and a sufficient control will not be obtained.

The main object of the present invention is to provide a simple device for correctly controlling the movement of the flag of the wrapper until it is completely wound about the head of the cigar bunch. Another object of the invention is to provide a wrapping mechanism of `the general character indicated above with an anti-friction the wrapper from its support to the head of a bunch.l Still anotherv object of the invention vis to provide a wrapper tension plate, formingpart of said wrapping mechanism, with a movable carrier for vconveying the-wrapper flag in the manner mentioned above. With these and other objects not specifically mentioned in View, the invention consists in certain-constructions, combinations and'parts whichwill be hereinafter fully described and then specifically set .forth in the claims hereuntoappended'.

. In the drawings, Fig. 1 is a perspective view of a device constructed in accordance with the inventioni Fig. 2 is a perspective view of another embodiment of theinvention; Fig. 3l is a perspective view of the embodiment shown in Fig. l1, showing v a nicked wrapper flag just before being wound aboutthe bunch head; Fig. 4 is an end view of the embodiment shown in Fig. 1, showing the flag of the wrapper just being releasedfrom the wrapper support; Fig. 5 is an end view of a modified form of the wrapper tension plate; andFig. 6 is an end view of another modified form ofv thev invention. Referring to the drawings, 1 indicatesyan almost completely wrapped bunch inl a rolling mechanism forming part of a wrapping mechanisrn. The rolling mechanism comprises bunch v rollers 7 mounted in a frame 11 in a manner Well known in the art and therefore needing no further description herein. There is also provided avwrapper supportS, provided withV means as for f instance a-suction surface forv holding a wrapper in outstretched condition thereon. The suction pipe is indicated 35. The wrappersupport and 5 the mechanism for establishngsucton therein ycarrier-forv conveyingthe rearor flag-end ofv Yfrom this specification.

a cam disc 13 is secured by means -a curvature 14.- The lever 16,

Vsecured tokone of the pins 9,

are well known in the art, and further description thereof is not needed herein. y

There is further provided a tension plate 3. This plate runs in a guide 33 and has a movementV by which it is periodically brought into a position adjacent the rollers '7. To this end a cam disc 25 is ksecured by means of a screw 24 to a shaft 12 rotatably journaled in the frame 11 and driven in any well known manner. A lever 27, 29 is pivoted to a shaft 15, its arm 2'7 having a roller 28 and its other arm 29 conveying the wrapper tension plate 3. The roller 28 is forced against the circumference Vof the disc 25 by a tension spring 30, one end of which is connected at 31 to the arm A27 and its other arm at 32 to the frame l1. The disc 25, isl provided with an extension 26. The end of the wrapper tension plate 3 adjacent the head of the cigar bunch 1 is somewhat curved downwardly and provided with a rollervlO having pins 9 rotatably journalled in the tension plate 3. 75 The cylindricaly surface of the rollerv projects slightly above the surface of the wrapper tension plate.

It will be understood that the wrapper is held by suction in outspread condition upon the operating surfaceof the Wrapper support 8 throughout the greater part of the relative crossing movement of said support and the bunch rolling vmechanism whereby y the Wrapperl is delivered from the Vsupport t0 a bunch in the rolling mechanism. It may here be remarked that themechanism by which this relative crossing movement vis produced is Well known in the art, and therefore description. and illustration thereof'is omitted 90 A`V lever 16, 21 is pivoted to the shaft 15. The freeend of the lever arm 16 has a rollerV 17 and the free end of the lever arm 21 has a friction surface 22 adapted to be periodicallybrought into engagement with the roller 10. To ythis end of a screw 23 to the shaft 12 and the roller 1'7 is forced against the peripheralY portion of the disc 13 by a tension spring 18Y connected to the arm 161 at 20 and to the frame 11 at 19. Thecam disc. has 21 and cam disc 13 may, underV certain circumstances, be omitted if according to Fig. 5 one end of a spring 34 is its other end being connected to the ytension plate 3. v

In operating themechanism illustrated in Figs. 1, 3 and 4, the wrapper held outspread uponvthe operatingV surface of the support 8 is' moved in the direction of the arrow to about the poit0n villustrated in Fig. 4. Then the wrapper 1 10 .fell

`the point of the incision,

tension plate has been moved by arm 29 into a position adjacent the rolling mechanism, and is resting in such position. Thereby the operating surface of the support 3 is forcing the rear wrapper end 6 and the flag 4 of the wrapper against the cylindrical surface of the roller l0, and as they are both provided with paste applied thereto before the wrapper delivery begins, they adhere both to said cylindrical surface, and thus they are successively drawn from the operating surface of the wrapper support as the roller is caused by the preceding wrapper support to rotate in the direction of the arrow (Fig. 4). Thus the wrapper flag is successively bent down from said operation surface when the support moves in the direction of the arrow, and it is not instantly pulled down or released from said surface. Therefore the operating surface of the support may act on the wrapper end and guide it until the wrapping operation is almost completed. On account of its structure, the roller l0 catches, carries and guides the dag of the wrapper and after having been nally relased from the operating surface of the support, that is, when it has passed the uppermost position or" the roller, the ag of the wrapper is still carried down by the rotating roller and applied to the head of the bunch.

After the wrapper end having `neen released from the wrapper support, the roller 17 enters the curvature ill of the continuously rotating cam disc 13 and the surface 22 of the lever arm 2l engages the roller le, thus arresting its rotary movement. At this moment, ir" the rear end of the wrapper is provided with an incision, the partly severed part of the wrapper iag has been bent down below the roller as shown in Fig. 3, and the point of the incision may coincide with the apex of the bunch. As the angular position of the cam disc 13 on the shaft 12 can be regulated, it is, however, possible to fix, as desired, the point of time when the surface 22 engages the roller 10.

At this moment the wrapper tension plate 3 is held by the arm 29 in its front position adjacent the bunch, as the roller 23 is forced by spring against the concentrical part of the cam disc 25. Now a reversed movement is irnparted to the tension plate by means of the cam disc 25, the projection 26 of which forces the lever arm 27 upwards, and a reversed rotary movement as indicated in Fig. 3 is imparted to the roller 10, which rolls upon the surface Then the partly severed flag end of the wrapper resting on roller 10 performs a swinging movement in the direction of the arrow (Fig. 3) round and is conveyed (carried) by the rotating cylindrical surface of the roller lo until the point of the part 4 of the flag has left the roller and is completely and correctly wound about the head of the bunch.

If a spring 34 is connected to the roller 1G as illustrated in Fig. 5, the same function is obof the bunch.

ne illustrated in Fig. 2 the anti-friction carrier may be developed as a roller lo, mounted in the frame 1l, adjacent the rolling mechanism.

One end of a spring 35 is secured to the pivot 9, its other end being connected to a bracket 36 carrying the pivot 9.

In operating the device shown in Fig. 2 the Wrapper flag is transferred and supplied to the roller in the same manner as previously described and bent down towards the head of the bunch by the rotating roller 10, which rotates tightening the spring 35. VJhen the wrapper support 8 has passed the roller 10 the latter obtains a reversed movement and the part 4 of the wrapper is Wound about the head of the bunch.

.As illustrated in Fig. 6 the roller 10 engages the upper surface of a bar 37 in the frame 1l. When the wrapper tension plate is moved towards the rolling mechanism, as the roller 28 is io ced against the concentric circumference of the cam disc 25, the roller engages the upper surface of the bar 37 and is imparted a rotary movement in the direction of the arrow, thus conveying the nag of the wrapper towards the head of the bunch. When the roller 28 is forced outwardly by the projecting portion 26 of the cam disc 25, a reversed movement is imparted to the wrapper tension plate, and thereby the roller l() rolls on the bar 37 in a reversed direction, thus conveying the last part of the flag of the wrapper to finish the wrapping operation.
